The National Medal of Science is an honor bestowed by the President of the United States to individuals in science and engineering who have made important contributions to the advancement of knowledge in the fields of behavioral and social sciences, biology, chemistry, engineering, mathematics and physics. The twelve member presidential Committee on the National Medal of Science is responsible for selecting award recipients and is administered by the National Science Foundation (NSF).

The National Medal of Science was established on August 25, 1959, by an act of the Congress of the United States under Public Law 86-209. The medal was originally to honor scientists in the fields of the "physical, biological, mathematical, or engineering sciences". The Committee on the National Medal of Science was established on August 23, 1961, by executive order 10961 of President John F. Kennedy.

On January 7, 1979, the American Association for the Advancement of Science (AAAS) passed a resolution proposing that the medal be expanded to include the social and behavioral sciences. In response, Senator Ted Kennedy introduced the Science and Technology Equal Opportunities Act into the Senate on March 7, 1979, expanding the medal to include these scientific disciplines as well. President Jimmy Carter's signature enacted this change as Public Law 96-516 on December 12, 1980.

In 1992, the National Science Foundation signed a letter of agreement with the National Science and Technology Medals Foundation that made the National Science and Technology Medals Foundation the metaorganization over both the National Medal of Science and the very similar National Medal of Technology.
